Humalog Mix 75/25 - DOES THE INSULIN DRUG OF HUMALOG OR LANTUS HAVE ANY MIXTURE OF AMPHETAMINE'S?

I have a friend that is diabetic, we had gone for a job that required a swab drug test, (he has not contributed to any other type drugs then his rx). All his lines came up on the test BUT the line for AMPHETAMINE"S. He had explained what he was on, but they did not hire him till he provides proof of the drug listing's. It really hurt him to see he cannot get hired a job that requires a swab if this is the reason, and as a friend it bother's me to see this happen. If anyone has any insight please help with this so I can rest peaceful knowing that someone is trying and not getting approved. Thank you
